title: Validation of the Spanish version of Ureteral Stent Symptom Questionnaire: prevalence of symptoms in a tertiary care center in Mexico.
abstract: OBJECTIVE
  To develop and to validate the Spanish version of the Ureteral Stent Symptom Questionnaire (USSQ). Describe the prevalence of symptoms associated with the presence of ureteral stent in a Spanish-speaking population.
  
  
  METHODS
  We developed and delivered the Spanish USSQ version to patients who underwent ureteral stent placement after endourological procedures. We determined the internal consistency and the instrument's sensitivity to change. Results of the patients were compared with a control group of healthy individuals. We analyzed the prevalence of symptoms in the six domains of the questionnaire and the overall quality of life. We compared the means of the results by gender to find significant differences in associated symptoms.
  
  
  RESULTS
  We obtained good internal consistency values of the instrument. Significant differences were obtained after sensitivity to change analysis in the scores of all domains except sexual performance. The correlation between the domains of urinary symptoms, pain, and general health was high. The analysis of specific symptoms showed important affection in all domains, being more significant in urinary symptoms and pain. The ureteral catheter also affected the daily life and work performance. There were no significant differences when comparing the symptoms by gender or age.
  
  
  CONCLUSIONS
  Spanish version of the USSQ is appropriate for assessing the symptoms associated with ureteral stent in the Spanish-speaking population. The ureteral catheter significantly affects the various aspects of life in this population.
